ANDERSANDERSON, OF BROOMFIELD, COLORADO.

CALENDAR.

T 0 all whom it may concern:

Be it known that I, ANDERs ANDERsoN, a citizen of the United States of America, residing at Broonifield, in the county of Adams and State of Colorado, have invented certain new and useful Improvements in Calendars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in calendars, and more particularly to that class of calendars, shown and described 'in Patent No. 716166, issued to me on the 16th day of December, 1902 and consists of a pocket device so arranged as to be capable of daily adjustment and provided with dials upon which is indicated the day of the week, the month of the year, the day of the month and the year of the century; upon a second dial is indicated the number of years, months and days which have elapsed since any predetermined date or event, as the birth of a person.

My improved device is constructed for continuous operation in the performance of its function. The mechanism is arranged so that in counting time, months containing thirty one days are considered, as the majority of the months are of this class. Provision, however, is made for interrupting certain parts of the mechanism in the case of those months having less than thirty one days as April, June, September, November and February.

The invention consists further in certain details of construction whereby the calendar maybe manipulated, all of which I will now proceed to describe in detail reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure 1 is a front face view of my improved calendar viewed in the direction indicated by the arrow A in Fig. 2. Fig. 2 is a central section taken through the line 22 of Fig. 1. Fig. 3 is a view looking in the direction indicated by the arrow B and at the plate where the arrow heads terminate. Figs. 4, 5, 6 and 7 are views looking in the direction indicated by arrows O, D, E and F respectively, and at the plates where the arrow heads terminate. Fig. 8 is a detail Patented Dec. 10, 1907.

1 view of a single toothed gear of which there are three employed in the mechanism for indicating the days in each week. Fig. 9 is an enlarged detail view of the mechanism emparts to indicate the days in each week, being an enlargement of that shown in Fig. 4. Fig. 10 is an edge view of the mechanism shown in Fig. 9. Fig. 11 is a detail face view of a leaf spring employed. Figs. 12, 13 and 14 are enlarged views of three special gears employed for the automatic adjustment of the parts to indicate the days in each week.

The same reference characters indicate the same'parts in all the views.

Let the numeral 5 designate a cylindrical casing within which is inclosed three disks designated 6, 7 and 8 respectively. These disks are connected by binding posts 9, holding them at suitable distances apart. The operating mechanism of the calendar is mounted on and between these disks.

Passing through an opening formed in the side of the casing is a spindle 10 whose inner extremity is secured to a movable plate 11, and whose outer extremity is made fast to a spherical knob 12 which protrudes from the casing and is employed in operating the device. This knob and spindle are slidable longitudinally, whereby the movable plate 11 may be reciprocated, its travel being limited by the pins 13-43 which are secured in the disk 6, and pass through elongated openings 11 11 formed in the plate 11. A ring 14 is attached to the casing after the manner of a watch ring.

Projecting from the inner extremity of the sliding plate 11, is a tooth 11 which engages a gear wheel 20 fast on an arbor 21 journaled in the disks 6, 7 and 8. The late 11 is held in operative engagement witli the gear 20, by a spring A, one extremity of which is connected with the plate 11 as shown at A while its opposite extremity is connected with the disk 7 as shown at A This movable plate is provided with a bearing edge 11 which the spring A engages. As the stem 10 is pulled outwardly the extremity 11 of the operating plate acts to turn the Wheel 20 one cog or tooth, while the inward movement of the stem 10 causes the tooth 11 to slip over the gear 20 sufliciently to be in position to give the wheel 20 a similar movementwhen the stem is next pulled outwardly. In this way the wheel 20 may be rotated by a step by step movement or ployed for the automatic adjustment of the vthe longest month as shown in Fig. 1.

another, upon the dial part 24".

one tooth at a time through the instrumentality of the actuating plate 11. The plate 20 is locked against movement in the reverse direction or in thedirection opposite the arrow in Fig. 3, by a spring pawl A mounted on the disk 7. On the arbor 21 are two loose gears 22 and 23 located outside of the disks 6 and 8, respectively. Outside of the gears 22 and 23 are locatedtwo dial plates 24 and 25.

Formed on the dial 24 around its outer edge are numerals consecutively arranged from 1 to 31 designating the days of The dial plate 24 is seen through a crystal 26 set into one side of the casing 5. The arbor 21 passes through both dials 24 and 25. T 0 its extremities protruding beyond these dials, are attached the hands or pointers 27 and 28. The outer extremity of the hand 27 points to the numerals indicating the days of the month. The portion of the dial 24 indicating the days of the month is designated 24 in Fig. 1. A portion 25 of the dial 25, is dividedinto thirty one spaces in any one of which spaces a numeral may be placed indicating the day of the month to be recorded viz. In the present instance the fourteenth day of the month is'indicated, by the numeral 14 which is placed in the portion 25 as shown in Fig. 7 at a point directly .opposite the numeral 14 on the dial 24, and indicating the fourteenth day of the month. The hand 28 is attached to the arbor 21 so as to travel in unison with the hand 27. On a central portion 24 of the dial 24, surrounding the arbor 21 and concentric with the part 24, are arranged numerals from 1 to 20 designating years. Between the parts 24 and 24 are formed auxiliary dials 24 24 and 24 Upon the auxiliary dial 24 are letters indicating the days of the week. These are arranged so as to indicate the lapse of two weeks or a fortnight for each revolution of the arbor carrying its indicating hand or pointer 42.

Upon the auxiliary dial 24 are formed numerals indicating months, while upon the auxiliary dial 24 are formed numerals designating the years of a century. The loose gear wheel 22 is provided with a hub 22 upon the outer extremity of which. is mounted a hand or pointer 28*, whose outer extremity is located adjacent to the auxiliary dial 24 Every time the gear wheel 20 is turned the distance of one tooth the hand 27 is moved from one number to Secured to the gear wheel 20 and traveling with it, is the single tooth .or arm 30 .(see Fig. 3) which engages a small gear 31 fast on the spindle 32, every time the gear 20 makes a complete revolution turning the gear 31, the distance of one tooth. On the respective extremities of this spindle 32 are made fast two hands or pointers 33 and. 34. The hand 33 is located adjacent the auxiliary dial- 24 Every time two arms or teeth designated 35 and 36 which engage the gears 22 and 23 respectively, and move each gear the distance of one tooth every time the spindle 32 completes a rotation indicating that a year has elapsed. After the spindle 32 has made one revolution the gear 22 will have been moved the distance of one tooth and its hand 28 will have moved from one numeral to the next of the dial 24. The gear 22 is supposed to have twenty teeth. When the last named gear has moved one complete revolution, the hand 28" will have moved entirely around the auxiliary dial 24. Made fast to the gear 22, is an arm 37 which engages a toothed wheel 38 and moves said wheel one tooth every time the wheel 22 completes a revolution or every twenty years. The dial 24 is provided with numerals indicating years expressed in multiples of twenty. On

the hub of the wheel 38 which is journaledin the disk 6, is mounted a hand 29- which points to the numerals 20, 40, 60 and 80 of the auxiliary dial 24 Mounted on the arbor 40 and meshing with the gear 20 (see Fig. 3) is the gear wheel 39.

The arbor 40 extends through the .disks '6 and 7 and protrudes through the dial part 24 of the dial 24. The gear 39 is provided with fourteen teeth. A similar gear 41 (see Fig. 4), has fourteen teeth and is provided with a sleeve 41 which is loosely fitted over the arbor 40 and is journaled in the disk 6 anddial 24. The sleeve 41 also protrudes through the dial 24 and the outer extremity of this sleeve is provided with a hand 42 which points to the letters indicating the days of the week on the auxiliary dial 24 A-small plate or disk 43 is fast on the arbor 40 and rests between the loose gear 41 and the disk 7. This plate is provided with a bow-spring 43 the free end of which engages the teeth of the loose gear 41, and by reason of its tension carries said gear with it at each movement of the arbor 40 unless said gear is otherwise retarded as will be hereinafter explained.

On the arbor 21 are rigidly mounted three short arms or teeth 44, 45 and 46, which en gage three small gear wheels 47, 48 and 49 respectively. These gear wheels 47, 48 and 49 are loosely mounted upon the spindle .50 and are held from accidental displacement by the leaf spring 51. The arms or teeth 44, 45 and 46, are so disposed on the arbor 21 as to have their teeth successively engage the respective gear wheels in succession as the arbor 21 is actuated. The gear wheels 47, 48 and 49 are each provided with twelve teeth. As the arbor 21 turns the tooth 44 into engagement with its gear 47, said gear is turned one-twelfth of a revolution, and at the next movement of the arbor 21 its tooth 45, turns the gear 48, the distance of one tooth; and at the third movement of the arbor 21, the tooth 46 turns the gear 49 the distance of one tooth. Thus it will be seen that as the arbor 21 makes a complete revolution, each of the gears 47 48 and 49 will have been turned the distance of one tooth and will be given a complete rotation for every twelve rotations of the said arbor. The gear 47 is provided with five teeth 47 extending beyond its remaining teeth and the gears 48 and 49 have one tooth each 48 and 49 respectively, ex tending beyond their remaining teeth. 'l'hese gears 47, 48 and 49 communicate with the loose gear 41 through the instrumentality of an escapement lever 52 which is pivoted on the plate at the point 53 (see Figs. 4 and 9) and held normally out of engagement with the gear 41, and in position to be engaged by the extended teeth of the gears 47 48 and 49 by the leaf spring 54. The engaging end of the escapement lever 52 is so placed adjacent to the gears 47, 48 and 49 as to be engaged only by the extended teeth 47, 48 and 49. In this manner it will be seen that as the extended teeth of the said gears pass the lever 52 they will cause said lever to engage the gear 41 and hold the latter stationary against the tension of the spring 43 also holding the hand. 42 mounted on. the sleeve 41 which,

points to the letters indicating the days of the week on the auxiliary dial 24.

To more clearly describe the arrangement just outlined it will be assumed that the various parts are in position to indicate the first days of January. The gears 47, 48 and 49 will be inthe position shown in Figs. 12, 13

and 14 from which it will be seen that as each gear is advanced the distance of one tooth by their engaging teeth 44, 45 and 46 respectively, that none of the extended teeth have been brought into engagement with the escapement lever 52. Hence the gear 41 has not been retarded and the thirty one days of January have been successively indicated on the dial 24. As the arbor 21 is again rotated indicating the second month. (February) of the year it will be seen that as each gear 47, 4S and 49 is successively ad vanced the distance of one tooth a second time that one of the extended teeth 47 a of the gear 47 and the extended teeth 48 and 49 will be brought successively into engagement with the lever 52 causing it to successively retard the gear 41 with its hand 42, for three successive operations of the device. As these three operations are given to the device on the first day of the succeeding month (March) thus advancing the hands 27 and 28 over the spaces 29, 30 and 31 of the dials 24 and 25 and retarding the hand 42 on the dial 24 maintaining the proper sequence of the day of the week commencing the first day of March. As the gears 48 and49 have but one extended tooth each, it will require a complete revolution of the gears 48 and 49 or twelve revolutions of the gear 20 before they will again cause the gear 41 to be retarded; but as the gear 47 is provided with five extended teeth 47, this gear will retard the gear 41 five times, the extended teeth being so disposed around the wheel as to engage the escapement lever 52 on the last of February, April, June, September and November.

On the outer face of the dial plate 25 as shown in Fig. 7, are found three small dials 56,57 and 58. On the dial 56 are formed numerals designating the years from 1 to 20. On the dial 57 are formed numerals designating years in multiples of twenty, while on the dial 58 are formed numerals designating months from 1 to 12. The dial 56 corresponds with the auxiliary dial 24 on the dial plate 24. The wheel 23 which is loose on the arbor 21, as aforesaid, is actuated from the spindle 32 by the .toothed arm 36. Every time the spindle 32 makes one revolution, the wheel 23 is moved one tooth and designates a year on the dial 56. To the wheel 23 is made fast an arm 59 which engages a toothed wheel 60 and moves the latter one tooth every time the wheel 2300mpletes one revolution. On the spindle 61 of the wheel 60 is mounted a hand 62 which points to the dial 57. A pointer 34 mounted on the spindle 32 points to the dial 58. The use of the various dials on the dial plate 25 and the mechanism employed in connection therewith, is to indicate the number of years which elapse since any given event, as the birth of a person, while the days of the week, months of the year and years of the century are indicated on the opposite dial plate 24. The pointer 34, on the spindle 32 consists ofa small disk, having a pointed projection 34* which points to the numerals indicating the months of the-year and the said disk is secured to the spindle 32 by a key 64. This key 64 forms an auxiliary indicator and is so set in relation to the disk 34 as to indicate the month of the year to be recorded when the pointer 34 is at the first month. Thus showing that the recorded month has been reached when the auxiliary pointer 64 points to the first month. The key 64, is secured in place to the disk 34, by a set screw 65,.(see Fig. 7) which is threaded through the key 64 and into one of the holes 34.

When the hands or pointers 28, 34, 62 and 66 are properly set with reference to the event to be recorded, it is evident from the description heretofore given that these hands will be operated in harmony with the hands 27, 29, 33 and 42 by the reciprocating movement of the knob 12. The side of the casing opposite the crystal 26 is covered by a screw cap 67 which must be removed to disclose the dial plate 25. If desired a transparent crystal may be employed in place of this cap. In Fig. 7 of the drawing the dial shows the date recorded as the 14th of the month and the key pointer 64, indicating the eighth month when the pointer 34 is at the first month, showing that Aug. 14th is the date recorded, and as the pointers 62 and 66 indicate that twenty three years have elapsed since the recorded date and the key 64 indicating eleven months after the last recorded year and the pointer 28 indicating seven days. since the last recorded month, showing the exact time elapsed since the recorded date as twenty three years eleven months and seven days.

From the foregoing description the operation of my improved device will be readily understood. Assuming that the parts are properly assembled, one reciprocation of the knob 12, acting on the operating plate 11 which engages the gear 20, moves the hands 27, 28 and 42 one space, indicating one day, on their respective dials. The wheel 20 has thirty-one'teeth and every time it completes a revolution, the hands 33 and 34 indicate the lapse of one month on their respective dials 24 and 58. The wheel 31 has twelve teeth and every time it completes a revolution the hands 28 and 68 on the dials 24 and 56 are turned one space indicating the lapse of one year on each dial.

The gear wheels 22 and 23 have each twenty teeth and every time they complete a revolution the hands 29 and 62, indicate the lapse of twenty years.

It will be seen that the proper sequence of the days, of the week and days of the month and months of the year is maintained by the single operation of the knob 12, the retarding of the hand 42, essential when months have less than thirty one days, being automatically effected, through the gearing 44, 45, 46, 47, 48, 49 and escapement 52, as above described, whereby the day-indicating pointer is prevented from registering a day at the beginning of each month having thirty days, and from registering three days at the beginning of February. N o provision is made in this calendar for leap years or when February has twenty nine days. It will thus be seen that the single toothed gears 44, 45 and 46, are arranged in the planes of the gears 47, 48 and 49, respectively and therefore actuate the said gears during the operation of the device. For every rotation of the arbor 21, each of the gears 47, 48 and 49 will be ac tuated. or moved one tooth or cog. The five auxiliary teeth-of the gear 47, and the single auxiliary tooth of each of the gears 48 and 49, are so arranged that one of the auxiliary teeth acts on the escapement 52 at the beginning of the registration of each month hav ing thirty days, during the operation of the device, and causes the escapement to act on the gear 41 whereby the last named gear is prevented from turning the day indicating hand 42, without interfering with or interrupting the movement of the other parts of the device. Four of the auxiliary teeth of the gear 47 act on the escapement 52 to hold the gear 41 at the beginning of the registration of the months April, June, September, and November while the fifth auxiliary tooth of the gear 47 acts in'conjunction with the two auxiliary teeth of the gears 48 and 49, the three acting in succession on the escapementto hold the gear 41 from registering three days at the beginning of the month of February.

It is believed that this explanation is as definite and specific as it is practicable to give.
